OHIO ADJUSTABLEAUXILIARY NOZZLE FOR SUCTION CLEANERS Application filed October 8,1924:. Serial No. 742,315.

An object of my invention is to provide an improved means for adjustingthe nozzle of a suction sweeper, wherein ease and certainty ofadjustment are the rime requisites.

Other objects and advantages of'the structure herein disclosed will beevident from a description of the structure shown in the drawings,wherein Fig. 1 is a side elevation of a suction sweeper showing theapplication of a preferred embodiment of my invention;

Fig. 2 is a partial plan View of the structure shown in Fig. 1; and

Fig. 3 is a fragmentary view of a portion.

of the structure shown in Figs. 1 and 2.

In the drawings wherein like reference characters refer to like partsthroughout, a

suction cleaner is shown which is indicated generally by referencecharacter 10. This suction cleaner 10 comprises the usual parts such asa drum 11 defining a fan chamber, motor 12, intake nozzle or hood 13,carrier wheel 14: and castor wheel 15, all parts of an ordinary cleaner.

Depending from the drum 11 of the suction cleaner are walls or flanges62-62 extending rearwardly from the nozzle 13 on opposite sides thereofwhich have bottom edges substantially in the plane of the bottom ofnozzle 13. Positioned upon the flanges 62-62 are lugs 66-66 adapted tofunction as hereinafter described.

. Positioned within the nozzle 13 with its rear wall positioned betweenthe depending flanges 62-62 is the adjustable auxiliary nozzlecomprising end plates 60-60, strip 63 connecting the forward ends ofplates 60-60 and the rear member 61 which serves as a bottom plateforming, with the walls 6262, a

an air passage leading from the nozzle inlet formed by the openingbetween the forward edge or lip 61 of 61 and the lower edge or lip 63 ofmember 63. The air passaqe is bounded on the sides-by the side walls60-60 and on the top by the nozzle 13 and drum 11 between the nozzleinlet and the eye of the fan chamber. It is to be noted that the sidewalls 60-60 extend rearwardly at the sides of member 61 within the walls62-62 and are per-' pendicular to the plane of the nozzle inlet as isthe connecting strip 63. Positioned upon member 61 are lugs 64-64 sopositioned relative thereto that when the auxiliary nozzle is placed inoperative position in the machine said lugs are adjacent thecorresponding lugs 66-66 on the flanges 62-62 of the drum 11. Extendingthrough the pairs of lugs 66-66 and 64-64 is the pivot pin 65 whichsupports the rear end of the auxiliary nozzle and about which saidauxiliary nozzle is adapted to pivot.

Fixedly attached to the underside of bottom plate 61 forward of thepivot pin 65 is the rod 67 which extends rearwardly through an openingin the rear wall of the hood 13. The end of the rod 67 protrudes beyondthe rear wall of the hood and is threaded as at 69 and mounted thereonin threaded relation is a knurled nut 70 adapted to be rotated thereonto effect adjustment of the auxiliary nozzle.

The agitating rotor 71 is carried in the nozzle. 13 by the side Walls60-60 which are provided with suitable agitator supportreceiving slotsindicated at 72. The agitator is of the usual type being provided with abelt-receiving pulley 73 near its center which is connected by means ofa belt 7 4 to the driving motor of the machine as in the usualcleanerconstruction. The agitator is so positioned relative to theauxiliary nozzle that its periphery extends substantially into the planeof the nozzle inlet formed by the lips 61 and 63 and is adapted tocontact the surface covering undergoing cleaning therebetween.

When in the operation of the machine it becomes desirable to raise orlower the nozzle month relative to the floor surface covering saidadjustment is obtained with ease in a cleaner embodying the presentinvention. It is only necessary to adjust the nut 70 upon the projectingend of the rod 67 to effect the desired adjustment of the mouth as anymovement of the rod 67 relative to its opening in the hood 13 results ina corresponding adjustment of the height of the inlet mouth within themain nozzle through the pivoting of the auxiliary nozzle about its pivotpoint.

I The construction is such that the auxiliary nozzle fits closely withinthe main nozzle 13 preventing air leakage therebetween and the bottommember 61 completely closes the bottom of the nozzle except for thespace between its forward edge and the member 63 known as the inletmouth.

I claim:

1. A suction sweeper having a main frame member defining a fan chamber,a forwardly extending open bottom nozzle hood, a suction passageconnecting the fan chamber and nozzle hood, the suction passage definedin part by walls depending from the fan chamber, an auxiliary nozzleintake having its forward and its side edges defined by wallssubstantially perpendicular to the plane of the nozzle intake, and therear edge defined by a flat unobstructed plate member having its forwardportion substantially in the plane of the nozzle intake, the auxiliarynozzle pivotally mounted at substantially the rear of the nozzle hood,the unobstructed flat portion of the auxiliary nozzle comprising incooperation with the depending walls a portion of the suction passage, arod fixed to said auxiliary nozzle and arranged to extend rearwardly andin close relation to a portion of saiimainirame member at a pointsubstantially above where said auxiliary nozzle is pivotally mounted,and means adjustable in connection with said rod and co-operating withsaid main frame member to raise and lower said auxiliary nozzle intakewith respect to said nozzle hood.

2. In a suction cleaner having an open bottomed main nozzle, anauxiliary nozzle pivoted therein and forming a bottom therefor, saidauxiliary nozzle comprisin a plurality of walls extending perpendicuarly to the plane of the supporting surface and a plate membercooperating with said walls to define an intake mouth for said nozzle,and adjusting means to position said auxiliary nozzle within said mainnozzle comprising a rod fixedly attached to said auxiliary nozzle andextending rearwardly therefrom through said main nozzle and adapted tobe moved therethrough to pivot said auxiliary nozzle about its pivotpoint.
